Which number from the set {0, 2, 3, 4} makes this inequality true? 6x − 10

Alex purchased 3 packs of baseball cards that cost $2.50 each. He also purchased 2 packs of card protectors that cost $3.00 each

vampirchik [111]

Answer:

6.50

Step-by-step explanation:

You have to add/multiply 2.50 by 3 to get the total cost of the cards. 2.50*3=7.5. then, you need to add/multiply 3.00 by 2 to get 6. 7.5+6= 13.5. 20-13.5=6.50.

the change was $6.50

Nick needs to raise at least $320 for his trip. He has $80 saved already, and he makes $40 per yard that he mows. Write and solv

Anestetic [448]

Answer: Nick must now at least 6 yards.

Step-by-step explanation:

Since Nick has $80 saved already, and he makes $40 per yard that he mows, thus can be put up in an equation as:

= 80 + 40y

where y = number of yards

Since Nick needs to raise at least $320 for his trip, the equation to solve this will be:

80 + 40x ≥ 320

40x ≥ 320 - 80

40x ≥ 240

x ≥ 240/40

x ≥ 6

Therefore, Nick must now at least 6 yards.

A line passes through the points (−4, −1) and (−2, −4) . Fill in the boxes to complete an equation for the line in point-slope f

gizmo_the_mogwai [7]

Here, first we need to calculate for Slope:
m = y2-y1 / x2-x1
m = -1-(-4) / -4-(-2)
m = 3 / -2
m = -3/2

Now, y - y1 = m(x - x1)
y + 1 = -3/2(x + 4)
y + 1 = -3/2x - 6
y = -3/2x - 7

In short, Your Equation would be: y = -3/2x - 7

Hope this helps!

Without exponents logc (xy^6z^-4) what is the equivalent expression

Sever21 [200]

By eliminating exponents, the logarithmic expression $\log_{c} x\cdot y^{6}\cdot z^{-4}$ is equivalent to the logarithmic expression $\log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z$ .

<h3>How to simplify logarithmic functions</h3>

In this problem we are supposed to eliminate all exponents of a logarithmic function by applying any of the following properties:

㏒ x · y = ㏒ x + ㏒ y
㏒ x/y = ㏒ x - ㏒ y
㏒ yˣ = x · ㏒ y

Now, we proceed to simplify the function:

$\log_{c} x\cdot y^{6}\cdot z^{-4}$

$\log_{c} x + \log_{c} y^{6} + \log_{c} z^{-4}$

$\log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z$

By eliminating exponents, the logarithmic expression $\log_{c} x\cdot y^{6}\cdot z^{-4}$ is equivalent to the logarithmic expression $\log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z$ .
